The Venn diagram compares aerobic respiration and anaerobic respiration.Which statement could be categorized only in the anaerobic section of the Venn diagram?

is performed by eukaryotes

has commercial uses

regenerates NADH

occurs in the mitochondria

Which is required for both anaerobic respiration and aerobic respiration?

oxygen

water

mitochondria

glucose

What do aerobic respiration and anaerobic respiration have in common?

Both begin with glycolysis.

Both occur in mitochondria.

Both require oxygen to proceed.

Both end with the electron transport chain.

The graphic shows the citric acid cycle. During the citric acid cycle, what happens to acetyl-CoA?

It enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4-carbon molecule.

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

It enters glycolysis and associates with a 5-carbon molecule through redox reactions, forming another acetyl-CoA molecule.

It enters the citric acid cycle and associates with a 4-carbon molecule, forming a 5-carbon compound, and then through oxidation reactions regenerates the 4-carbon molecule.

Which statement about cellular respiration is true?

It produces oxygen.

It requires water.

It is used by every living cell.

It converts energy to food.

The Venn diagram compares aerobic respiration and anaerobic respiration.Which statement should be categorized only in the aerobic section of the Venn diagram?

occurs in the cytoplasm

produces water

requires no oxygen

is performed by yeast

During which process is water produced?

alcohol fermentation

acetyl CoA formation

electron transport chain

citric acid cycle

What role does cellular respiration play in the water cycle?

It removes H2O from the atmosphere during glycolysis.

It removes H2O from the atmosphere during acetyl CoA formation.

It releases H2O to the atmosphere during the citric acid cycle.

It releases H2O to the atmosphere during electron transport.
